The Stanley Tumbler is made out recycled stainless steel. The tumbler is able to hold up to 40 oz of any liquid. There is a double-wall vacuum insulation that allows your drink to stay cold for 11 hours or 7 hours hot. The comfort-grip handle makes it convenient and comfortable to carry. The tapered bottom allows it to fit into most cup holders. 

Details:

• 90% recycled 18/8 stainless steel, BPA-free
• Recycled stainless steel icon inside the tumbler indicates your Quencher is made from sustainable materials
• Double-wall vacuum insulation
• Powder coat finish
• FlowState™ screw-on 3-position lid
• Reusable straw
• Comfort-grip handle
• Car cup holder compatible (base diameter: 3.1 inches)
• Dishwasher safe

The 40 oz tumbler costs $40 which is a reasonable price for the quality of the cup compared to its competitors like Yeti and Hydroflask: it is double the size. The tumbler also has prettier choices compared to the options of the other brands.

Overall I would recommend the Stanley 40 oz tumbler to anyone who’s in the market for a new tumbler. It does exactly what it’s advertised to do, keep your drink at its desired temperature for hours. I would rate this cup a 5/5.
